Shenyang J-11B/BH/BS/BSH Flanker B/C+

New build Shenyang J-11B Flanker B fighter. The missile under the wing is a
Chinese
clone of the Rafael Python 3 heatseeking missile. The J-11B
aircraft are typically painted in different tactical camouflage to the
J-11A,
with a medium blue grey upper surface, light grey lower surface, black
radome, while the half ellipse grey area on the nose is overpainted
with uniform camouflage (Chinese internet images).

Introduction

The controversial J-11B is an unauthorised derivative of the
Sukhoi J-11A/Su-27SK, built by Shenyang in China. The aircraft has been
the subject of an ongoing dispute between Beijing and Moscow which has
caused the suspension of production of the second batch on indigenously
manufactured legally licenced J-11A/Su-27SK.

The J-11B is not an exact clone of the Su-27SK, despite the
commonly held view this is so. The airframe and engines can be
considered to be 'cloned' but the systems are mostly unique to this
variant.

Known differences include:

A Chinese IRST set located in the centreline position as
with the OLS-27 in early Su-27S.

A planar array multimode radar which resembles the
Phazotron Zhuk-27 series. It includes an IFF interrogator array.

An Onboard Oxygen Generator System (OBOGS). Only the most
recent Russian variants have an OBOGS.

A unique glass cockpit design, with an asymmetric layout
quite different from the Su-30MKK/MK2 and Su-27SMK.

An optical MAWS system claimed to operate in the UV band.

Dielectric panels on the stabilators not seen on any
Russian variant.

The differences between the J-11B, Su-27SK and Su-27SMK are
sufficiently great that this must be considered a unique offshoot of
the Flanker family of fighters, not a subtype of the baseline
Su-27SK/J-11A.

Chinese sources claim that the J-11B variant deployed with
PLANAF units, such as the 22nd Fighter Regiment, 8th PLAN Fighter
Division, is designated the J-11BH.

In 2011 images emerged of the prototype of the J-11BS which is
an analogue of the Su27UBK, with the PLANAF variant claimed to be the
J-11BSH.
